Embodiment Construction
[0019] see figure 1 , this embodiment provides an underground pressure-compensated spring root irrigation emitter, which can be buried underground with the capillary system. The buried pressure-compensated spring root irrigation emitter is a combined structure, including a connector 1, a pressure-compensated emitter core 2 and an upper cover 3. The order of pressing the three underground is the connector 1, the emitter Core 2, upper cover 3. The connector 1 and the emitter core 2 are connected by screws, and the emitter 2 core is inserted into the upper cover 3, and the two are tightly sealed. The emitter is directly connected to the capillary tube through a 20 joint, and a matching pp cotton sleeve is included on the outside, so that the water flow from the buried pressure-compensated spring root irrigation emitter slowly infiltrates into the surrounding soil and avoids root system and soil intrusion.
[0020] see figure 2 , image 3 , the emitter core 2 is integrated w...

The invention discloses an underground pressure-compensating bubbler root irrigation device, comprising a connection piece. An irrigation device core and an upper cover form a combined structure, the connection piece is connected with a capillary pipe through a joint, the irrigation device core is connected with the connection piece through a screw, and the connection piece is provided with a water inlet; and a maze runner in an inclined tooth shape is distributed on the irrigation device core, and filter screen grids and a pressure compensating area are arranged in the pipe. The working principle of the underground pressure-compensating bubbler root irrigation device disclosed by the invention is as follows: water flow in the capillary pipe is divided and then enter the irrigation devicecore through the water inlet of the connection piece, directly attacks an elastic membrane sheet in the irrigation device core, enters the maze runner through the filter screen grids to dissipate energy and then flows out through a runner outlet communicated with a lower cavity, wherein the elastic membrane sheet is deformed due to the attack function of a pressure water flow so as to press a round water outlet to change overflow area, and thus a function of pressure regulation is realized; and the water flow subjected to energy dissipation flows out of an overflow hole and then permeates into the soil.
Description
technical field [0001] The invention belongs to the technical field of agricultural economic forest irrigation in arid areas, and particularly relates to an underground pressure-compensated spring root irrigation device, which is suitable for solving the irrigation problem of mountain economic forests. Background technique [0002] As the most water-saving irrigation technology, micro-irrigation is adopted for the irrigation of more and more types of field and commercial crops. According to the water requirements and irrigation systems of different crops, the development of corresponding emitters is the demand for the development of micro-irrigation. [0003] Satisfying a certain uniformity of irrigation is one of the important indicators of micro-irrigation design, that is, no matter how the working pressure of the emitter changes, each plant should receive almost the same amount of irrigation. Micro-irrigation in mountainous economic forests has three characteristics. One ...
